Simultaneous use of thyme essential oil and disodium fumarate can improve in vitro ruminal microbial fermentation characteristics
Two trials were conducted to investigate the effects of disodium fumarate (DSF; 0.00, 8.00, 10.00 and 12.00 mM) and thyme essential oil (TEO; 0.00, 100.00, 200.00, 300.00 and 400.00 µL L-1) solely and simultaneously (10.00 mM DSF along with 100.00, 200.00, 300.00 and 400 µL L-1 TEO) on in vitro ruminal fermentation of a 50:50 alfalfa hay to concentrate diet. The D...
متن کاملEffects of forage particle size, level of feed intake and supplemental protein degradability on microbial protein synthesis and site of nutrient digestion in steers.
A 2(3) factorial arrangement of treatments was used to study main effects and interactions between particle size of prairie hay (chopped vs ground), two levels of feed intake (60 and 90% of ad libitum) and ruminal degradability of protein sources [dry corn gluten feed (DCGF) vs dry distillers grains (DDG)] on ruminal and total tract digestion in eight ruminal- and duodenal-cannulated steers. St...
متن کاملEffects of Thyme Essential Oil and Disodium Fumarate on Ruminal Fermentation Characteristics, Microbial Population and Nutrient Flow in a Dual Flow Continuous Culture System
The aim of the present study was to investigate the effects of di-sodium fumarate (DSF) and thyme essential oil (TEO) solely and simultaneously on ruminal fermentation properties and microbial abundance. A dual-flow continuous culture system (DFCC) with eight 1400-mL fermenters was used in a period of 12 d that divided to 9 d for adaptation and 3 d for sampling. Fermenters were fed 100 g d...
متن کاملThe Effect of Soybean Meal Heating Time on the in vitro Digestibility and Ruminal Fermentation Profile
The aim of this study was to determine the most optimal heating time in protection of protein rich feedstuff on digestibility and in vitro ruminal fermentation profile. Proteinous feedstuffs used in this study is soybean meal (Glycine max). This study is designed using one way ANOVA, with five treatments of heating time (T0 (control)= unheated, T1= 10 min, T2= 20 min, T3= 30 m...
متن کاملThe Effects of Use Medicinal Plants on Rumen Fermentation Parameters in Ruminants
Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...
